Question

In a phased migration strategy, why should refactoring be completed before transformation begins?

Accepted Answer

Because wca4z cannot process COBOL programs until they are registered in the IBM Refactoring Assistant catalog — Think of it like working hands-on with IBM mainframe systems — the answer here is 'Because wca4z cannot process COBOL programs until they are registered in the IBM Refactoring Assistant catalog'. Refactoring before transformation establishes stable service contracts. If boundaries are redefined after Java code is generated, significant rework is required, so investing in boundary definition fi. On real mainframe exams, this concept comes up repeatedly so make sure you have it locked in.

Answer

Because the IBM watsonx platform requires COBOL source to be pre-processed by Refactoring Assistant before receiving transformation prompts

Answer

Because completing refactoring first establishes stable service boundaries, reducing rework if boundaries change after Java code is already generated

Answer

Because refactoring automatically removes all CICS EXEC commands that would otherwise cause wca4z to fail
